摘　　要：采用一柱两用分析生成 γ 丁内酯、合成 α 乙酰 γ 丁内酯两个反应产物体系 ,可以简化操作方法 ,提高分析效率。Butanediol, γbutyrolactone in reaction mixtures from the preparation of γbutyrolactone and αacetylγButyrolctone, γbutyrolactone and solvent in resction mixtures from the preparation of αacetylγButyrolctone were determined by GC with TCD.The analytsis operation condition was set up on a 1m×Φ3mm stainlesssteel column packed with signizied 102 white support coated with polydiethylene glycol succinate. This method has the features of simplicity,rapidity and accurcy.
